Figure 13 is a fragmentary sectional view "illustrating the manner in which the present invention is applicable to a railway car having a movable ost disposed intermediate of a relatively wi e doorway, which type of car I is frequently designated as an automobile car.

Referring first to Figure 1, the numeral indicates a side wall of the car and the numeral 2 indicates as a whole a door. The door 2 is a sliding door, and according to the form illustrated in Figures 1 and 2 is supported at the top, rollers 3-3 being provided, which rollers engage with a track member 4 (Figure 2) The partlcular track member illustrated is the A. R. A. standard and is provided with the vertically dlsposed portion 5, which is secured to the car structure. Projecting outwardly from the vertlcally disposed portion 5, intermediate of the widthof said portion 5, is the horizontally disposed portion 6, upon which the rollers 33 are carried. According to the 7, which not only perform the function of carrying the rollers 3-3, but serve as gussets, in amanner which will be referred to hereinmeans for a roller 8 adapted to have rolling engagement with the under side of the hori zontally disposed portion 6. The rollers 3 Said supporting members 7-7 not and 8 cooperate to hold the door in its proper vertical position.

' wardly along its lower edge for the reception of the upper flan e 13 of the rib member 14, which member 14 is disposed horizontally. The front and rear edges of the plate 12 are swedged forwardly in a diagonal direction, as indicated by the numeral 12 (Figure 12) 'The upper flange 13 of the rib member 14 and the lower extremity of the plate 12 are secured tothe plate 15 at the upper portion of said plate 15, said plate 15, upper flange 13 and lower extremity of the plate 12 being disposed in the order named, reading from the inside of the door to the outside thereof. The intermediate portion of the plate 15 is secured to the lower flange 13 of the rib member 14. The plate 15 is substanti 11y flat and may be of the same dimensions s plate 12. the lower extremity of the plate 15 being swedged outwardly for the reception of the upper flange 16 of the rib member 17 and the upper edge portion of the plate 18. Secured to the upper flange16 of the rib member 17v and to the lower extremity of the plate 15 is v the plate 18, the upper portion of said plate 18, the upper flange 16, and the lower extremity of the plate 15being disposed in'the order named, reading from the inside of the door to the outside thereof. The lower flange 16 of .the rib member 17 is secured to an inter- .rear edges of the door are the pressed steel rib members 24 and 25, respectively.' Figure.

- 12 gives a good idea of the cross sectional contour of said members 24 and 25. It will be noted from an inspection of said figure that the member 24 has the forwardly extending flange 26 with the turned back lip portion 27, which lip portioncooperates with the pressed steel member 28, which member 28 is fastened to the body of the car. The pressed steel I member 28 is provided with the lip portion 29 adapted to have sealing relationship with the lip portion 27 of the rib member 24. The

member 28 is fastened to the structural steel member 30, which member 30 is provided with the filler post 31. The rib member 24 is provided with the laterally extending flange 32, which is shaped to conform to the horizontally disposed rib members 9, 14, 17 and 20 above described. In the forming operation performed upon the member 24,the portions 33 which overlie the horizontally disposed rib membersmay, as indicated in the drawings, be swedged to have a width slightly greater than the width of the remainder of the rib member 24, whereby to provide added hearing surface upon said horizontally disposed rib members.

The vertically disposed rib member 25 is fashioned in the manner described in connection with the rib member 24, in a number of respects, the flange 32 and the portions 33 thereof being identical with the structure discussed in connection with the rib member 24. The flange 26' of the rib member 25 is provided with the li portion 34, which is turned inwardly of t 1e car instead of outwardly. The rib members 24 and 25 may be identical except as regards the lip portions 27 and 34, thereby simplifying the matter of manufacture of the door. The lip portion 34 of the rib member 25 is adapted to cooperate with the pressed steel member 35, which member 35 has the lip portion 36 adapted to cooperate with the lip portion 34. Said member 351's secured to the structural steel member 37 which member 37 is provided with the filler post 38.

The numerals 3939 indicate reinforcing members which in practice take the form of small castings. Several of said members 39 are disposed in spaced relationship within the rib of the members 24. Rivets 40 secure said members 3939 to the forward face of the.

door. Rivets 41 secure the diagonally disposed portion of the rib member 24 to said reinforcing members 39. By reason of the expedient of riveting through the diagonally disposed portion of the rib member 24 between the flange 32 thereof and the forward face, round head rivets may be used without increasing the overall transverse dimensions 1 of the door. Inasmuch as the reinforcing members 39-39 are subjected to compressive forces, the castings referred to will be found to be well adapted for the purpose. It will be noted that the rivets 41 secure together the reinforcing members 39, the horizontally disposed sheets (12, 15 or 18), and the rib member 24.

The rib member 25 is provided with spaced reinforcing members 42-42, which may be pressed steel members shaped to conformto the space within said rib member 25. One

extremit of each of the steel members 42 is riveted, y means of the rivets 44, t'oa transversely disposed portion of the rib member 25. The other extremities of the steel members 42 are riveted, by means of rivets 43, to

the diagonally disposed portion of the rib member 25, which diagonally disposed portion is indicated by the numeral and lies between the flange 32 and-the outer face of said rib member 25. Disposed between said diagonally disposed portion 45 and thereinforcing members 42 are the outwardly flanged edge portions, such as 12*,- of the horizontally disposed sheet metal members 12, 15 and 18. Several of said reinforcing members 42-42 are provided in spaced relationship with one another. I

The corner construction at the four corners of the door may be varied considerably. According to Figures 1 and 2, the castings 7-7 serve not only formounting the rollers 3 and 8, but also perform the functions of gussets, said castings being securely riveted to the adjacent portions of the rib members 9 and 24 or 25 and the adjacent plate 12. According to Figure 3, a sheet metal gusset 46 is provided which is securely riveted to the adjacent parts to form a rigid corner construction.. Said gusset 46 may be used at any or all of the four corners.

Figure 9 shows acorner eonstruction wherein the rib member 9 is extended over a .rib to the rib member 24, said rib member 9 having a portion 46 of greater width than the remainder of the rib member 9 to provide greater bearing surface. The corner construction illustrated in Figure 9 can, of course, be used at all corners of the door.

Figures 10 and 11 illustrate a bottom supported structure, a casting 47 being provided at each lower corner of the door for supporting the roller 48, which roller 48 rides upon the track member 49' secured to the body of the car. Said casting47 may be provided with the lip 50 cooperating with a portiomof the track member 49 to limit outward movement of the door at the bottom thereof. Said casting 47 is securely riveted to the adjacent rib members and sheet metal plate, whereby to perform the functions of a gusset.

Figure 13 illustrates an embodiment of the present invention appliedto a car having a movable post, which caris'commonly designated as an automobile can The movable post referred to is a steel member and is indicated by the numeral 52and has fastened thereto the filler post 51. Said steel member 52 has secured thereto the steel member 53, provldlng a lip portion 54 for cooperation with the lip portion 27 of the door. According to the embodiment of the invention illustrated in Figure 13, the post 51 has an auxiliary door 55 secured thereto. I Said auxiliary door 55 may be of substantially the same construction as that discussed above inconnection with the door 2. According to the illustrated embodiment, the rib member 56 at the right-hand. edge of the auxiliary. door 55,"

as the parts are viewed in Figure 13, is very similar to the rib members 24 and 25, but has the plain flange 57 secured .to the steel members .52 and 53- Moreover, the sheet metal platemembers forming the main portion of the door hasportions'extended inwardly, as indicated by the numeral 58, which portions are riveted to the steel member 52.
